| Fixed In Version: | Doc Type: | Bug Fix | |
| Doc Text: |
Cause: livenessProbe fails when prometheus is under heavy load, such as WAL replay.
Consequence: Prometheus gets restarted, exasperating the load issue due to repeated WAL replay.
Fix: Remove livenessProbe.
Result: Heavy load no longer causes the livenessProbe to fail in turn avoiding restart loops.
